  • 천북지역을 포함하여 경주시를 중심으로 선상지분포와 지형발달을 조사하였다. 선상지는 하상비고가 다른 고위면. 중위면, 저위면의 세 지형면으로 구분된다. 불국사∼울산지역과 마찬가지로 빙기와 간빙기가 반복된 제4기 기후변화와 북-남 및 북서-남동 방향의 구조선이 탁월하게 발달하면서 합류선상지가 형성되었다. 단일 규모로는 우리나라에서 최대급에 속하는 경주선상지는 선사시대 이래 인간활동의 중심 공간을 제공하였다. 이 선상지를 형성한 북천은 선사, 고대에 거의 범람하지 않았다. 경주선상지는 지형면 전체에서 지하수위가 지표면 부근까지 도달하여 일반적인 지형특성과 달리 선앙부에도 용천이 분포한다. 이것은 유역분지의 상류부와 중류부에 넓은 퇴적 공간이 형성되어 있어 북천 규모에 비해 하류부에 퇴적물이 충분히 공급되지 못한데 기인하는 것으로 판단된다.

  • In order to verify the enhancement of ozone and carbon monoxide (CO) during springtime in East Asia, we investigated weather conditions and data from remote sensors, air quality models, and air quality monitors. These include the geopotential height archived from the final (FNL) meteorological field, the potential vorticity and the wind velocity simulated by the Meteorological Mesoscale Model 5 (MM5), the back trajectory estimated by the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model, the total column amount of ozone and the aerosol index retrieved from the Total Ozone Mapping Spectrometer (TOMS), the total column density of CO retrieved from the Measurement of Pollution in the Troposphere (MOPITT), and the concentration of ozone and CO simulated by the Model for Ozone and Related Chemical Tracers (MOZART). In particular, the total column density of CO, which mightoriginate from the combustion of fossil fuels and the burning of biomass in China, increased in East Asia during spring 2000. In addition, the enhancement of total column amounts of ozone and CO appeared to be associated with both the upper cut-off low near 500 hPa and the frontogenesis of a surface cyclone during a weak Asian dust event. At the same time, high concentrations of ozone and CO on the Earth's surface were shown at the Seoul air quality monitoring site, located at the surface frontogenesis in Korea. It was clear that the ozone was invaded by the downward stretched vortex anomalies, which included the ozone-rich airflow, during movement and development of the cut-off low, and then there was the catalytic photochemical reaction of ozone precursors on the Earth's surface during the day. In addition, air pollutants such as CO and aerosol were tracked along both the cyclone vortex and the strong westerly as shown at the back trajectory in Seoul and Busan, respectively. Consequently, the maxima of ozone and CO between the two areas showed up differently because of the time lag between those gases, including their catalytic photochemical reactions together with the invasion from the upper troposphere, as well as the path of their transport from China during the weak Asian dust event.

  • The purpose of this study is to present the implications of the rural living area setting and rural spatial structure analysis of the rural spatial strategy plan through case analysis. Following the decentralization of autonomy and the promotion of the transfer of state affairs to local areas, some of the general agricultural and fishing village development projects of the Ministry of Agriculture, Food and Rural Affairs were transferred to local areas. In addition, in 2020, the Ministry of Agriculture, Food and Rural Affairs introduced a rural agreement system for 113 cities and counties. However, since the understanding of the field is still low, this study attempted to present implications through a case analysis of the structure of rural space and the establishment of rural living areas in three local governments in Chungcheong. As a result of the study, in the stage of establishing the living zone, it is necessary to comprehensively review the contents reviewed in the analysis of the current status and conditions. However, the two local governments had insufficient interpretation of the axis by function and the establishment of the base area, or were using the upper plan as it was. Second, the source of the data used in the survey on the distribution status of living SOC facilities is unclear. Since the distribution status of living SOC facilities overlaps with accessibility analysis, OD data analysis, and resident survey results and is used as the basis for setting living areas, the data source should be clearly marked, and verification should be possible. Third, amenity (facility) resources were classified and analyzed according to the conditions and characteristics of local governments. The local government that applied the guidelines as they were was A local government, and the remaining local governments conducted surveys and analysis according to the current status. Forth, since the establishment of the rural living area is the minimum unit supported by government policies through future rural agreements, it is necessary to distinguish them based on quantitative standards in the process of establishing them. Only one case area presented clear grounds and standards, and the rest of the case areas presented standards but are based on non-quantitative standards. In order for rural agreements to be sustainable in the future and benefit local residents, it is necessary to use or establish a government-level institution that can collect and produce objective data. In addition, it is necessary to find ways to specify and standardize the standards for setting the living area and specify them in the guidelines.

  • Fasciola hepatica is a trematode that causes zoonosis, mainly in cattle and sheep, and occasionally in humans. Few recent studies have determined the infection status of this fluke in Korea. In August 2015, we collected 402 samples of freshwater snails at Hoenggye-ri (upper stream) and Suha-ri (lower stream) of Song-cheon (stream) in Daegwalnyeong-myeon, Pyeongchang-gun in Gangwon-do (Province) near many large cattle or sheep farms. F. hepatica infection was determined using PCR on the nuclear ribosomal internal transcribed spacer 2 (ITS-2). Among the 402 samples, F. hepatica 1TS-2 marker was detected in 6 freshwater snails; thus, the overall prevalence in freshwater snails was 1.5%. The prevalence varied between collection areas, ranging from 0.0% at Hoenggye-ri to 2.9% at Suha-ri. However, F. gigantica ITS-2 was not detected in the 6 F. hepatica-positive samples by PCR. The nucleotide sequences of the 6 F. hepatica ITS-2 PCR-positive samples were 99.4% identical to the F. hepatica ITS-2 sequences in GenBank, whereas they were 98.4% similar to F. gigantica ITS-2 sequences. These results indicated that the prevalence of F. hepatica in snail intermediate hosts was 1.5% in Gangwon-do, Korea; however the prevalence varied between collection areas. These results may help us to understand F. hepatica infection status in natural environments.

  • The purposes of this study are to comprehend the importance of policy in improving the operation of the public arboretum and survey the program satisfaction of participants and operators based on the case of the Daegu arboretum. According to the order of policy priority regarding the Daegu arboretum, the expansion of the education program topped the list with 0.155 points, followed by the establishment of a vision and goal, and the reestablishment of function, which scored 0.135 and 0.135 points, respectively. Fostering citizens' participation through volunteer work was in the upper ranks with 0.131 points. Building networks among public arboretums and constructing a research cooperation system with universities turned up with 0.09 and 0.075 points. As the result of program satisfaction, participants' satisfaction was around 0.66 points higher than that of operators' satisfaction. In the case of participants, comprehensive satisfaction, including that with the program operation method, was very high at 4.85 points. Out of the entire program, the operators were the most satisfied with the benefits. This study aims to share improvement plans for public arboretums constructed in urban areas, analyzing policy priorities and satisfaction related to the Daegu arboretum. The results of this study can be utilized as data for the improvement plans of public arboretums. If improvement plans for public arboretums are modeled with other follow-up case studies, it will help ensure that public arboretums become evolving rather than fixed areas for citizens.

  • Purpose: This study was to examine the possibility of the contact with pornographs of elementary school boys and girls and to confirm responses after that, and to compare the feeling of sexual conflict between the boys and girls. Methods: The subjects were 952 5th and 6th graders of elementary school in four city areas(456 boys, 496 girls). Data collection was via questionnaires Results: Except several pupils(34.4% of boys, 27.4% of girls), most of subjects of the study had no contact with pornographs. The response after the contact with pornographs was feeling of shame the most, which was a negative reaction. The sexual conflict appeared more in pupils who had contact with pornographs than in those who had not boys(t=3.84, p<.000), girls(t=3.96, p<.000), which showed a significant difference. However, the conflict between boys and girls was not significant statistically. Conclusion: We would like to suggest that a sound control system must be prepared and a development of programs related to sexual education and promotion of ability fighting against them that can release their impulse of sex.

  • The demand for a construction method capable of securing a safety environment and improving quality is increasing. There is a high risk of falling when working at a high place in an environment where it is difficult to secure visibility, such as an underground space, and there is a risk of falling if cement liquid waterproof materials are transferred to the top of the scaffold by manpower. In addition, when working on a high place in a poor environment, the quality uniformity of the upper part of the wall is deteriorated. In addition, as waterproof technicians gradually age and decrease, it is difficult to secure them, so it is urgent to prepare countermeasures against the shortage of waterproof technicians. Therefore, the purpose of this study is to develop cement liquid waterproof spouting construction equipment that can secure uniform quality of construction areas to prevent accidents and ensure safety of workers, improve work efficiency and quality due to improvement of work environment. The adhesion performance of the cement liquid waterproof material could be improved by about 20% in accordance with the use of the equipment.

  • This study investigated the cognitive process of 5-year-old children, with a particular focus on gender, monthly age, and their tendencies towards hyperactivity through the performance of the Cognitive Assessment System (CAS; Das & Naglieri, 1997). The children with tendencies towards hyperactivity were identified based on Conners Teachers' Rating Scale (CTRS). The subjects were 75 five-year-old children in Seoul and surrounding metropolitan areas. Data were analyzed by means of descriptive statistics, an independent sample t-test, Pearson's correlation coefficient, one-way ANOVA, and by K-mean cluster analysis. Our results were as follows : (1) The CAS and CTRS' sub-factors were correlated negatively, except the positive correlation between planning factor and hyperactivity factor. (2) Girls exhibited significantly higher CAS scores in planning & sequential processing than boys. (3) The upper monthly age group (68-71 months) showed significantly higher score in terms of planning than the lower monthly age group (60-63 months). (4) The CAS scores of the children with tendencies towards hyperactivity was lower than that of normal children. (5) The CAS profile of 5-year-old children was divided into 4 groups with distinctive characteristics by means of K-mean cluster analysis.
